ELECTROLIER.

Specification of Letters latent.

Application filed August 10, 1911.

Patented Apr. 23, 1912. Serial No. 643,316.

To all whom 'it may concern:

Be it known that I, THOMAS P. STRIT'r- MATTER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have lnvented a new and useful Electrolier, of which the following is a specification.

This invention relates to electroliers and more particularly to a stand electroller adapted for use as a surface or central ornament for tables, stands and the like, and 1t has for an object to provide a novel and useful means of illuminating a table from the surface thereof and in connection with which many novel features of constructlon have been devised to accomplish the desired end.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustratlng my lnvention, I have shown in the accompanylng drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be var ously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrument-alities as herein shown and described.

Figure 1 represents a perspective partly in section of an electrolier embodying my invention. Fig. 2 represents a sectional elevat-ion of the base of the same. Fig. 3 represents a modification of the globe retaining means.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :-1 designates the base of an electrolier embodying my invention the same being provided with the legs, 2, of a suitable length to elevatethe body portion of the electroller a sufliclent distance above the supportlng surface to permit the fixture wires or cords, 3, to pass freely to a point of connection. It w ll be noted that the base 1, is perferably formed with an ornamental design, which enhances the appearance of the electrolier very materially, though of course it will be understood that the same is not absolutely necessary as far as the utility of the device is concerned. In the preferred form of my invention, the

base 1, is provided with an internal circumferential recess 4, the contour of which conforms substantially to the outer edge of a plate 5, which is seated within the said recess 4, thereby forming a close joint with the plate 5, and holding the same securely in place.

6 designates an annular seat, the diameter of which is preferably greater than the same dimension of the recess 4, in order to form a shoulder 7 against which is seated a retaining or backer member 8, the function of which is to lock the plate 5 in position, it of course being understood that the member 8, is soldered, cemented or otherwise fixedly secured to the base 1. Attention is here directed to the fact that the plate 5, is preferably formed as a mirror or reflecting surface, whereby the rays of light from a suitable lamp 9, or the like, are reflected, thus augmenting the field of the light by distributing the rays in all directions. As here shown, the lamp 9, is an ordinary, incandescent lamp mounted in the usual manner in a socket, 10, passing substantially through the center of the plate 5 and member 8, it of course being apparent that the same are apertured at 11 and 12 to receive the socket, which is retained in place by a screw threaded bushing 13, having a flange 14, thereon, the face of which engages the bottom of the member 8.

15 designates a lip preferably formed integral with the base 1, and overhanging the upper surface of the reflecting plate, 5, thereby forming an abutment 16, or the like, circumferentially disposed about the edge of the plate 5, and serving to retain the globe 17 in position upon the plate 5, and prevent displacement of the same, due to vibrations, shocks or the like.

In Fig. 3 I have disclosed a modification wherein the base 1, is used in connect-ion with a reflecting plate 5, which has a beveled edge 18, and therefore in lieu of the retaining lip 15, I preferably employ a spider 19, or the like adapted to fit over the socket-10, and be held in place thereby, while the arms 20, of the said spider terminate in upstanding lugs 21, within which the globe 17 is seated. In connection with this spider or tray 19, it will be noted that the arms 20 are preferably of flexible material and ofa. length sufiicient to fit the largest size of electrolier contemplated. By this construction it will be clear that the spider or tray may be used with the smallest sizes also, since the arms 20 may be bent to conform with the diameter of the globe used and still operate successfully and practically as a retaining means therefor.

In assembling the device, the plate 5 is placed in position within the recess 4 resting against the lip or overhang 15, after which the backer member 8 is seated on the shoulder 7 and soldered or cemented in place. The lamp socket 10 is then passed through the openings 11 and 12 and the bushing member 13, screwed on to bring the flange 14 into locking contact with the backer 8, whereby the latter and the plate 5 are securely fastened together intermediate their edges. The globe 17 may now be placed in inclosing position over the lamp, being supported by the reflecting plate 5 and held from lateral movement by the abutments 16 or lugs 21, as the case may be, depending on the form of construction employed.

It will now be apparent that I have devised a complete unitary structure well adapted for the purpose intended, in which a suit-able lighting fixture is embodied in a stand structure, having a reflecting surface positioned face upward to reflect the light rays, and materially increase the lighting effect. It will further be apparent that the pro-vision of an abutment or lip, on the base of the electrolier, overhanging the surface of the plate 5, provides a retaining means for the globe 17 and holds the same from lateral movement.

It will now be apparent that I have devised a novel and useful construction of an electrolier which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-

1. In an electrolier, a base having a recess therein, a plate seated in said recess and having an upwardly disposed horizontal refleeting surface, means to retain said plate in position, an illuminating device supported above said plate, a globe seated on said plate and inclosing said illuminating device, and a circumferential abutment secured to said base and adapted to prevent lateral movement of said globe.

2. In an electrolier, a base having a recess therein, a plate seated in said recess and having an upwardly disposed horizontal reflecting surface, means to retain said plate in position, an illuminating device supported above said plate, a globe seated on said plate and inclosing said illuminating device, and means to prevent lateral movement of said globe.

3. In an electrolier, a base having a recess therein, a reflecting plate seated in said recess having an opening therein, means to retain said plate in position, a socket passing through said opening and adapted to support an illuminating device above said plate, a flange bushing engaging said socket and adapted to retain said socket in position on said plate, a globe seated onsaid plate'and inclosing said illuminating device, and means secured to said base and adapted to prevent lateral movement of said globe.

4. In an electrolier, a base having a recess therein, a horizontal reflecting plate seated in said recess having an opening therein, means to retain said plate in position, a socket passing through said opening and adapted to support an illuminating device above said plate, means for holding said socket in position on said plate, a globe seated on said plate and inclosing said illuminating device, and means secured to said base and adapted to prevent lateral movement of said globe.
